EPHRAIM BALL, OF CLARKSVILLE, TENNESSEE, ASSIGNOR TO THE CLARKS- VILLEIRON WAGON MANUFACTURING COMPANY, OF SAME PLACE.

IMPROVEMENT IN VEHlCLE-AXLES.

Specification forming part of Letters Patent No. 168,208, datedSeptember 28, 1875 application filed March 6,1875.

To all whom it may concern:

Be it known that I, EPHRAIM BALL, of Clarksville, in the county ofMontgomery and in the State of Tennessee, have invented certain .new anduseful Improvements in Wagon- Axles; and do hereby declare that thefollowing is a full, clear, and exact description thereof, referencebeing had to the accompanying. drawings, and to the letters of referencemarked thereon, making a part of this specification.

The nature of my invention consist in the construction and arrangementof an iron axle for wagons, as will be hereinafter more fully set forth.

In order to enable others skilled in the art to which my inventionappertaius to make and use the same, I will now proceed to describe itsconstruction and operation, referring to the annexed drawing, in which-I Figure 1 is a side view of my improved iron axle. Fig. 2 is across-section of the same through the line to m, Fig. 1. Fig. 3 is asimilar section through the line y 1 Fig. 1.

A represents the axle, made of a single piece of iron, with flanges aand Z1 extending on both sides along the upper and lower'edges, asshown, making the cross-section of the form of a letter H. The ends ofthe axle are placed under a hammer and properly tapered flanges of thespindle, making a solid end and a perfect spindle as far back as theweld-piece B extends, except on the bottom, and at this point the circleis finished by bolting or riveting the bearing C. The front or outer endof the welded piece B is drawn-out, as shown at d, and a thread cut'on'it to hold the wheel on. At the back end of the spindle, after the tophas been ovaled, as shown, the side cavities are filled up by rivetingor bolting to the Web-blocks D D, of proper shape .to form a spindletheir entire length, as far around as to the bottom flange b of theaxle, and the circle is completed by the bottom bearing E being rivetedor bolted on and then, for the double purpose of helping to hold firmlyin their places said blocks and bearing, and to make a shoulder to thespindle, a band, G, of iron is shrunk around the entire spindle. Thisband is prevented from giving back from the thumping of the hub againstit by the taper of the irons around which it is shrunk. H represents theking-bolt, which is turned upside down, and the head riveted or boltedto the axle.

I do not broadly claim a wagon-axle made in the form of the letter H, asI am aware that such is not new.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

1. The axle A, formed with top and bottom flanges a b, and having itsends hammered down in tapering form, with the top flange a rounding tospindle shape, substantially as set forth.

2. In combination with the axle A, the end piece B, welded to the end ofthe axle and drawn out to form the screw 01, substantially as set forth.

3. In combination with the axle A, the side pieces D D, riveted orbolted to the axle, for the purposes set forth.

4. The bottom pieces C and E, in combination with axle A and thepieces'B and D D, substantially as and for the purposes set forth.

5. The band G, in combination Wlth lJhC axle A, side pieces D D, andbottom piece E, substantially as and for the purposes set forth.

6. The reversed king-bolt H, having its head fastened by rivets or boltsto the axle, substantially as set forth.

In testimony that I claim the foregoing I have hereunto set my hand this18th day of February, 1875.

EPHRAIM BALL.
